Enum UpsertEmulationPolicy

Namespace

LinqToDB

Assembly

linq2db.dll

Controls what happens when an Upsert cannot be expressed as a native single-statement upsert or MERGE for the target provider and would fall back to an emulated multi-statement SELECT → UPDATE → INSERT sequence. See UpsertEmulationPolicy.

Fields

Allow = 0

Perform the emulated multi-statement fallback (default). The statements run as independent commands; wrap the call in a transaction if atomicity is required.

Throw = 1

Reject the emulated fallback: throw LinqToDBException at build time instead.
